A device (200, 300) for mitigating a first group delay (τ1) of a lowpass filter configured to lowpass filter a first channel coefficient of a set of channel coefficients with respect to time, includes a prediction filter (203) configured to filter a data sequence ( x[k] ) derived from a lowpass filtered first channel coefficient (Formula (I), 204) to generate a prediction value (ĥ [k-τ2], 206) of the lowpass filtered first channel coefficient (Formula (I), 204); and an adjustment circuitry configured to adjust the prediction filter (203) to generate the prediction value (h [k-τ2], 206) comprising a second group delay (τ2) that is less than the first group delay (τ1). |
